I know right now cause of covid they have some free webinars on some interesting stuff, but it's mostly education on the stuff THEY make and do. I never thought that the fiber is just SDI through light. Thanks!

Multimode fiber is a lot more forgiving when it comes to connection points. Singlemode connectors really need to be cleaned each time they mate, moreso than multimode.

Just binged the trailer playlist and loved it, great job. We just ordered 6 Sony z280’s and I’m curious how you do com and return video if you are using the bmd 12g miniconverters.

Thanks for watching! Return video is easy. The 12G converters are bi-directional so you can both send and receive video at the same time. You'd probably want to find a different intercom solution if you aren't using Blackmagic's Camera Converter products with the built-in intercom capability. The number of devices needed to extract and embed audio from SDI for intercom would be awkward and prohibitive. Take a look at my recent video on budget intercom options for a little more info.

This is very helpful. I will say the converters are a bit more expensive than BNC cables. but likely way better too.

Another Great Video. Just a few minor items. 1. Multi-mode fiber is NOT older, Single Mode was developed in 1970, Multi-mode wa created in the 1980's to allow 10Mbs ethernet to to go 2km using CHEAP LED transmitters compared to the expensive transmitters needed for single mode. Now that Single-mode SFPs are reasonable there is no reason for Multi-mode except for use in existing systems where they did not have enough foresight to install single-mode alongside the multi-mode for future proofing. By the way Multi-mode fiber has always been more expensive, just able to use cheaper transceivers! 2. SMPTE Composite cable does not have additional fibers for return channels, ALL SMPTE Composite cables have 2 Single-mode fibers, 2 Larger conductors for power, 2 small conductors for data. The dat wires are often used to negotiate the power level to be used on the power conductors and to ensure power is turned off when disconnected, the fibers are often (Grass Valley & Sony & ?) tu send 3G SDI to and from the camera, typically one fiber is used to send HD SDI (720P, 1080i, or 1080P) to the Base Station, the other fiber is commonly used to send TWO 1.5G signals to the camera, the Monitor return and an aux return ( Teleprompter, Talent Monitor, etc.) The Viewfinder return path has a small router in the base station that can send any of 3 or 4 SDI inputs to the viewfinder. 3. SMPTE Composite cable can be used for any single=mode purpose with a set of adapters, very handy if you go somewhere that is prewired with SMPTE cable. 4. Cameras set up for SMPTE can be used over a pair of single-mode fibers. This requires local camera power and often some adapters to spook the safety system to think the small wires are present. 5. you can make your own SMPTE cable with a pair of single mode fibers and 4 copper conductors - this is sometimes done when pre-wiring a building. 6. Most single mode fiber SFPs can be used on multi-mode fiber. The distance will be almost as far as a multi-mode SFP ( way shorter than a Single mode SFP) and a special "launch Cable" should be used on each transmitter side. Another option when you get somewhere that has something installed that is not ideal but may make the impossible possible.

While the cable isn't expensive the convertors are which make running fiber more expensive that SDI IMO

Where can I buy a 1000 foot fiber optic cable reel? something identical to what you show in your video?

Hey Doug that was really informative. Couple of questions. What’s the breakout box used in venue with the 24 strand fibre cable? Does it only feed video and not power Like cat 6 poe for ptz? And how do you convert the OB trick side to capture the cameras into switcher. Cheers

@djp_video

Жыл бұрын

Ethernet is carried over two strands of fiber. Those are plugged into SFP modules in two Ethernet switches -- one in the trailer, one in the venue. The one in the venue has PoE functionality to power PTZ cameras, Dante AVIO devices, Dante-based intercom beltpacks, etc. (Those connections are actually a multi-VLAN trunk over a LAG for additional bandwidth and redundancy.) Video is converted between fiber and SDI using Blackmagic ATEM Studio Converters in the trailer, and ATEM Camera Converters in the venue. This provides video in both directions, intercom, tally, audio, and camera control. The breakout box just splits the 24 strands in my trunk cable out to individual duplex pairs, passively so it doesn't require any power. 11 of those pairs are for cameras/video, and one pair is for the Ethernet Trunk LAG. Aside from the network switch, there are no active components in the breakout box.

LC are the connectors used by the video equipment, so it makes a lot of sense to just stick with those for everything. It makes things much easier. I do have some LC-ST cables if I ever encounter a facility that already has its own fiber. The only fiber tool I have is a really basic cleaner I picked up off of eBay a couple years ago. It doesn't even have a manufacturer's name on it so I can't say who makes it.

I don't know that I'd recommend fiber if you're running an ATEM Mini... you'd spend a fortune in SDI-to-HDMI and HDMI-to-SDI converters on top of the fiber equipment. Fiber signals are actually SDI, so it's easy to adapt SDI connections. Not so easy to do HDMI. But, with that said, you'd either need SDI Fiber converters like the Blackmagic Optical Fiber 12G converters on each end plus 3G SFP modules for each, or an ATEM Studio/Talkback Converter plus an ATEM Camera Converter at each camera.

sfp compatibility problems always struck me as odd. It's always seemed like a lot of the point of sfp is that the devices which do actual work can be indifferent as to how signals are sent -- they just need to trust that the sfp module can handle the needed bandwidth and that a matching sfp module on the other end will vomit out the same signal. It should really just be as simple as choosing modules which can handle the needed bandwidth. And yet that doesn't seem to be the case.

Video SFPs have to deal with a different type of signal than those made for networking. They really do have to be designed differently. SDI signals look nothing like Ethernet and the circuitry has to accommodate that.

So, if you have two fiber cassettes both at each end, one as a remote press box with all of the cameras going into it and then you have an MTP cable running that to another cassette that sends video to the Studio Converter...on the press box side, are you able to connect a switch with a fiber port into that cassette and have another switch like that on the other side so you can send internet and Dante over? That question may sound odd but I really don't know how to word it.

@djp_video

They're just fiber lines and you can use them for anything you want. You just need a switch with an SFP port and an appropriate SFP module (single mode, LC connector, UPC in my case), or a media converter with appropriate SFP, on each end to provide a network connection. The role of the cassettes is to break the 12 (or 24) fiber lines in the MTP cable into individual pairs (6 or 12 of them) so standard duplex cables can be used to connect to the SFP modules. Alternately you can buy purpose-built fan-out cables and skip the cassette altogether.

Could the BMD gear be used with other video SFPs such as AJA? Also, could you output from a Camera Converter with a BMD SFP to say an AJA Fiber > SDI converter successfully?

​@@djp_video Yes it will work, but with a 1.25Gbit/s SFP (used for gigabit ethernet) you will only be able to transport HD-SDI (1,5Gbit/s, 1080i). With a 10G rated data SFP you will be able to use any SDI signal but the specified range might be a bit less with 12G-SDI as the frequencies are a bit higher. Because data SFPs are way cheaper I always would recommend simply buying these in 10G versions.

You can get SFP modules that are bi-directional which let you send signals in both directions over a single fiber strand. But I'm not aware of any intercom systems which use fiber natively. The Blackmagic system is the closest in that it lets you send video and intercom over fiber. And you can replace its SFPs with bi-directional versions if you'd like.
